summary
Shows concrete wins and failures: recommends Signal, WhatsApp, Wire for end‑to‑end chat, demos Facebook Messenger’s secret conversations, and documents email as largely unencrypted despite legacy SMTP.

Walks through deploying SPF DKIM DMARC and TLS, cites successful newspaper and provider rollouts after measurement and pressure.
